To ALL WHoM 1r MAY concurrir:

Be it -known that I, Quran B. Goonnun, of the city and county of St.Louis, in the State of Missouri,I

have invented anew and useful Improved Glass-Furnace, of whichthefollowiug is a full, cl'enrand exact' description,referencebei-nghad'to the drawing annexed, making a. part ofthi'sspecilicatiom'in which- Figure 1 represents a sectional sideelevation of my improved furnace.

Figure 2 represents a transverse section of my invention at a; as.Similar letters indicatelike parts. My invention consists inconstructing the pots and furnace used in manufacturing glass in suchemauncr Inlg. 1, A represents the {ire-box of my furnace; b b', thepots, formed of lire-clay, which are built into and make a part ofthefurnace itself, as shown by the drawing: The larger pot, having anopening'lat the top of the furnace, is fed from the'outside,while thesuiallerone is fed from the opening d, as well as thepartially-moltenglass owing from the inclining arch D, figs. 1 and 2.These pots, from .their position in the oven, are powerfully acted uponby the heat, and, being provided with'one o rv more outlets, shown atce' c cll will throw into the bottom of the v ats E,F, and the glass,properly melted to bereasily worked.-

I do not intend, in manufactura-to limit myslfto two pots, b'ut shalluse the number most convenient, and arrange them in the positions wherethey will best receive-the heat.

The openings or ports dddNZI' are used both for feeding the furnace andfor removing itscontents, when. properly melted, by means of the pipesor tubes usually employed. Through thc openings dr the shelf or arch D,figs. 1 and 2, is fed with the 'batch, which, as it melts, will flowinto the vat E, and pass thence into the vats F and G, the pots being soarranged as to' allow free circulation both of the heat and molten glassaround them on every side. v

I also construct my furnace with reverberatory'arches atfff, extendingentirely across the'furnace, as shown at gg', fig. 2. The heat, takingthe direction shown by the various arrows in fig. .1, is, by means ofthese `arches, rcverbcratcd upon the glass, thus materially aiding inmelting the same.

I do not intend toV limit myself to arches const :ructed perfectlyperpendicular, but may incline them as experience may dictate. i I

I also place a packing of sand under and around thebottom of the vats orfurnace, as shown in the draw-4 ing, which, by its impermeability, willeffectually prevent the escape of glass from the furnace, although thewalls` of same should crzicka-nd open. This lining is mudo when thefurnace is constructed, being built into it.

The advantages of thisconstruction of a glassfur-naee are manyantlo'bvious. The pots are stronger, more durable, less liable to bebroken or injured, and I do away with' the annoyance and delayoccasioned by the breaking of pots constructed in the old way. The heatcoming more immediately incontact with-the glass, landa greater surfaceof glass being exposed'to its action,-lcss fuel will be'required, andthe glass will be brought to n proper condition forwork'rng in lesstime-than when the 'old furnace is used. The sand lpacking rendersaccidents from the escape of the glass almost impossible, which is notthe case with other furnaces.

What I claimv as my invention, and desire to secure by Letters Patent,is.- i The-shelf D of a furnace formelting glass, asshown andspecified.v i

Tho combination of a furnace for melting glass with immovable pots, asspecified. l

. The employment of revcrberatory arches in a furnace for melting glass,arranged as specified.

. The packing of a furnace for melting glass with sand, as specified.

. A furnace for meltingglass, when constructed 'substantially'as shownand specified.
